barcarole:

From Boudin’s diary entry [Tuesday, December 3, 1856]: To swim in the open sky. To achieve the tenderness of clouds. To suspend these masses in the distance, very far away in the grey mist, make the blue explode. I feel all this coming, dawning in my intentions. What joy and what torment! If the bottom were still, perhaps I would never reach these depths. Did they do better in the past? Did the Dutch achieve the poetry of clouds I seek? That tenderness of the sky which even extends to admiration, to worship: it is no exaggeration.

Skies by Eugène Boudin, 1848-1853.
